Authorities say DNA testing at the state police crime lab has been hampered by the condition of the remains that may be decades old, and a positive identification is still pending.

The out-of-state work may take several weeks.

Police believe the remains discovered Oct. 22 are those of Kitty Wardwell. The storage unit was rented by her former boyfriend Frank Julian, who died Oct. 1 at the age of 80. Wardwell has been missing for 28 years.

Julian told investigators he last saw the 29-year-old Wardwell after an argument in 1983, when he dropped her off at a motel in Salem, N.H.
